Introducing the world’s first ultra-telephoto all-in-one zoom lens for the APS-C format. With a focal length range of 18-400mm and 22.2x zoom, it has an ultra-telephoto range equivalent to 620mm in the 35mm format. This brings distant subjects closer, while providing perspective-flattening effects that are only possible with an extreme telephoto lens. Plus it offers exceptional optical performance across the entire zoom range—from wide angle to ultra-telephoto. With this new lens—and its Moisture-Resistant Construction—Tamron brings the art of photography to the joy of travel. Now you can use the same lens to shoot everything from stunning landscapes and neon-lit cities to detailed portraits and delicate flora. The ultra-telephoto range makes it just as easy to photograph animals and sports. And with a maximum magnification ratio of 1:2.9, you can even enjoy tele-macro photography.

Single Camera & Lens - Travel Photography with Matt Granger

I took the Tamron 18-400mm super zoom lens along with the Nikon D500 to Hong Kong for a week to see if I can manage with a single camera and lens kit!

Introducing the world’s first ultra-telephoto all-in-one zoom with a focal length range of 18mm to 400mm. Now you can shoot everything from vast landscapes to the details on a bird with a single lens. The latest optical design includes elements such as LD (Low Dispersion) glass and aspherical lens. Moreover, problems like chromatic aberration and distortion are controlled throughout the entire zoom range, resulting in sharp, superior images—whether you’re shooting at wide-angle or telephoto. The lens also features a maximum magnification ratio of 1:2.9 so you can enjoy tele-macro photography.

620mm capability, compact size

Until now, shooting at ultra-telephoto ranges meant carrying large interchangeable lenses. Thanks to the all-in-one zoom technology developed by Tamron, you can travel with a single lens that’s 4.8 in long and weighs only 24.9 oz.* Experience the thrill of shooting with compact equipment that makes it easy to capture ultra-telephoto images.

* Length and weight are based on the Nikon-mount lens.

Three cams. One smooth zoom.

Our ultra-telephoto all-in-one zoom includes an all-new barrel design. By distributing complex movements across three cams, Tamron has ensured that all zoom extensions are smooth and easy.

HLD, or “High/Low torque-modulated Drive,” adjusts the motor’s torque to enable smooth autofocusing at high and low speeds alike.

■ HLD Features
HLD harnesses magnetic forces to create rotational force. Thanks to its unique magnetic circuit design, durable and compact HLD produces higher torque than a conventional DC motor. By controlling the current flow through the motor, rotations are smoother, allowing the motor to be driven quietly at both high and low speeds.

■ Small But Mighty
The HLD takes up less space, thanks to its small gear ratio and gear count - which plays a large role in reducing the size of the lens.

Sharp, solid telephoto shots

Simulated viewfinder image.

Tamron’s VC (Vibration Compensation) technology stabilizes the image in the viewfinder, so you can frame your subject and shoot a sharp image̶even at ultra-telephoto ranges and in poorly lit conditions.

Tamron wows the world again with our ultra-telephoto all-in-one-zoom

In 1992, all-in-one zoom lenses were known for their heavy weight, bulky size and mediocre performance. Tamron revolutionized the industry by creating a lightweight, compact, high-performance “all-in-one zoom lens” that was perfect for everyday use. It launched to worldwide acclaim, cementing Tamron’s role as a pioneer in the “all-in-one zoom lens” category. Whereas the zoom magnification was 7.1x in 1992, it has increased to 22.2x for the Model B028 which is the world’s first* to achieve 400mm at the telephoto end. With its advanced optical system, compact lens barrel, high-precision cam configurations and VC, the B028 introduces the next level of Tamron innovation: the “ultra-telephoto all-in-one zoom lens.”

Additional Features

For greater protection when shooting outdoors, leak-proof seals throughout the lens barrel help protect your equipment.

Compatible with the TAP-in Console™

The optional TAP-in Console provides a USB connection to your personal computer, enabling you to easily update your lens’s firmware as well as customize features including fine adjustments to the AF and VC.

An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is employed in Nikon-mount lenses*. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

MTF

Optical Construction (16 elements in 11 groups)

MTF Chart Guide

MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.

The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.

Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.

Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
